Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0029] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.
[0030] In one embodiment of the present invention, according to Figure 1-5 As shown, an underwater welding channel structure includes an underwater welding channel 100; the underwater welding channel 100 includes a welding channel head 110, a welding channel tail 130 and a welding channel middle 120; an underwater sealing structure 200 is provided on the underwater welding channel 100, and a welding channel working cabin 140 of a ship underwater structure 300 can be formed with the underwater welding channel 100 through the underwater sealing structure 200; the staff can operate the ship underwater structure 300 in the welding channel working cabin 140. The underwater sealing structure 200 is a sealing rubber with a tensile strength of ≥150Kg / cm2.
[0031] Specifically, by setting up an underwater welding channel 100 and an underwater sealing structure 200, the underwater structure 300 of the ship that needs to be operated can be tightly combined with the underwater welding channel 100, forming a sealed space welding channel working cabin 140, so that operations can be carried out in a sealed environment, and there is no need to move to land for construction operations such as closure and repair, which simplifies the steps of the operation and solves the technical problems of poor safety of underwater construction operations, difficult welding, and poor construction quality.
[0032] Furthermore, the sealing rubber has good sealing effect, good resilience and good tear resistance.
[0033] In another embodiment of the present invention, according to Figure 2 and 3 As shown, the cross-section of the middle part 120 of the welding channel is a U-shaped structure, and the middle part 120 of the welding channel includes a channel bottom plate 121 at the bottom and channel side plates 122 on both sides; a channel deck 123 is provided on the top of the two channel side plates 122, and an underwater sealing structure 200 is provided on the two channel decks 123.
[0034] Specifically, the middle part 120 of the welding channel is a U-shaped structure, and an underwater sealing structure 200 is provided on the channel deck 123. The underwater structure 300 of the ship is tightly fitted with the middle part 120 of the welding channel through the underwater sealing structure 200, blocking the U-shaped mouth, so that a sealed welding channel working cabin 140 is formed inside.
[0035] In another embodiment of the present invention, according to Figure 2 and 3 As shown, a channel ballast tank 1221 is provided in each of the two channel side plates 122. The channel ballast tank 1221 is used to provide buoyancy to the underwater welding channel 100 as a whole. The channel ballast tank 1221 can be adjusted by ballast water to adjust the overall underwater level and draft of the underwater welding channel 100. A channel partition plate 1222 is also provided in the two channel side plates 122. The channel partition plate 1222 divides the channel ballast tank 1221 into a plurality of sub-ballast tanks. Specifically, the plurality of sub-ballast tanks can be better dispatched and the ballast water adjustment can be better controlled to adjust the overall underwater level and draft of the underwater welding channel 100.
[0036] In another embodiment of the present invention, according to Figure 2 and 3 As shown, a reinforcement structure 1211 is further provided in the channel bottom plate 121, and the reinforcement structure 1211 is used to provide support force. Specifically, the reinforcement structure 1211 can be various reinforcement columns, etc., to increase the load and support force.
[0037] In another embodiment of the present invention, according to Figure 1-3 As shown, the length of the middle portion 120 of the welding channel is greater than the length of the underwater structure 300 of the ship. Specifically, the length of the middle portion 120 of the welding channel must be greater than the length of the underwater structure 300 of the ship. If it is less than, it is impossible to achieve reliable sealing with the underwater sealing structure 200 to form a sealed welding channel working chamber 140.
[0038] In another embodiment of the present invention, according to Figure 1-3 As shown, the two ends of the middle portion 120 of the welding channel are respectively welded to the welding channel head 110 and the welding channel tail 130, and the welding channel head 110 and the welding channel tail 130 are higher than the liquid surface and are divided into the freeboard of the underwater welding channel 100. Specifically, in the water, the liquid level of water cannot exceed the freeboard part. If it exceeds the freeboard part, water may flow into the sealed space, and the staff cannot perform operations in the welding channel working cabin 140.
[0039] In another embodiment of the present invention, according to Figure 5 As shown, the welding channel head 110 includes a head bottom plate 111 at the bottom and head side plates 112 at both sides; the head bottom plate 111 and the head side plates 112 at both sides form a head working cabin 113, and the head working cabin 113 is connected to the welding channel working cabin 140. The welding channel tail 130 has the same structure as the welding channel head 110.
[0040] Specifically, the front working cabin 113 is connected to the welding channel working cabin 140, and the workers can enter the welding channel working cabin 140 from the front working cabin 113 to perform construction work.
